BlueTEC

Lower emission levels thanks to innovative exhaust gas purification.

Variable like a van, robust like a light-duty truck: the Vario is the classic model in the van portfolio of Mercedes-Benz. A classic model that also reflects state-of-the-art in such important fields as fuel economy and emissions – thanks to BlueTEC BlueEFFICIENCY technology.

BlueTEC is the cutting-edge SCR diesel technology from Mercedes-Benz: an economical and ecologically convincing solution. The SCR (Selective Catalytic Reduction) exhaust-gas aftertreatment technique is the only technology that permits the necessary reduction in emissions while optimising engine performance and fuel consumption.

The BlueTEC system comprises state-of-the-art engines with enhanced peak pressures to improve combustion and reduce particulates. Other system components are a catalytic converter and an AdBlue® tank. This additive is simply obtained from a pump at a filling station and carried in a separate tank. A metering unit feeds it into the exhaust gas, whereupon the heat turns it into the ammonia needed for the chemical reduction in the catalytic converter. There the nitrogen oxides are converted by a catalytic chemical reaction into ecologically harmless nitrogen and water.
